Btrfs-progs: show generation in command btrfs subvol list

This adds the ability to show root's modification generation when we use
btrfs subvol list.

NOTE:
Like file's atime and ctime, root's generation also has 'creation generation'
and 'modification generation'.
The generation that we're going to show is 'modification generation', and the
next patch is going to show 'creation generation'.
